Title: Optical data transmission system using optical star coupler
Inventor: TAKEDA KAZUHIKO
IPC: H04B10/00
Filed: 1986-06-18
Abstract: PURPOSE:To simply execute the data transmission without giving adverse effect on an optical data signal with a fast response while the distortion in the optical data signal is reduced remarkably by always sending a specific idle signal to the photodetector side of each port of an optical star coupler. CONSTITUTION:An idle signal (i) is always sent from one station, e.g., an optical transmission terminal station SN among optical transmission stations S1-SN. The idle signal (i) has the same transmission speed as the optical signal (main signal), while its optical level is a specific quantity being 1/4-1/10 of the main signal. Thus, at the absence of the main signal, the receptions section of the stations S1-SN recive the idle signals (i), which have no significance as the signal but thrown away in the inside of the reception section. In sending the main signal from an optical transmission terminal station, the main signal and the idle signal (i) are superimposed in the optical star coupler C, but neglected because the threshold level discrimination of the photodetection section of the stations S1-SN gives a small value. The idle signal receiving state is always kept in the ATC(automatic threshold level control) of the light receiving section in such way.
